Paceman Gus Atkinson Exacerbates England's Fitness Problems.
'Major setback' for the touring side after Atkinson leaves the field suffering a hamstring problem.
The English seamer increased the injury concerns plaguing England when he left the playing area on the second morning of the Boxing Day Test against Australia.
The right-arm seamer experienced discomfort in his hamstring post-delivery in his spell at the MCG.
Team management reported the 27-year-old felt some "soreness" and was to take time off the field for further assessment "during the day".
The series decider in this Ashes battle beginning on 4 January begins at the end of the week.
England have been without key quicks one seamer due to knee trouble and another paceman to a side strain on the current trip.
Matthew Fisher was added to the party as cover for Wood.
His form was underwhelming during the first two matches, taking just a handful of scalps.
He was left out of the third Test, then recalled for the Melbourne Test as Archer's replacement.
The county bowler showed better form in Melbourne, claiming a couple of wickets during the host's first knock, then making 28 with the bat being one of only three teammates to reach double figures.
After bowling one over late on the first day, he returned for the second day's play and had nightwatchman edging to the keeper.
Yet, towards the conclusion of that over, he delivered a slower ball to Travis Head and suddenly grabbed his left hamstring.
Atkinson returned to the side for the fourth Ashes Test having missed the Adelaide game.
